Definitions

  • the present invention relates to an apparatus for positioning a workpiece relative to a treatment station. More particularly this invention concerns positioning the workpiece on a table of a stamping machine or the like.
  • a workpiece is held on a stamping machine or the like between two or more clamp members mounted on an elongated traverse that extends transverse to and that can move in a longitudinal direction toward and away from a treatment station on a table of the machine.
  • the traverse can be moved in the longitudinal direction to determine workpiece position in this direction.
  • the stops can be moved in the transverse direction along the traverse for positioning the workpiece in the transverse direction.
  • German patent document 3,634,255 describes such a system. It has a round-section guide rod extending in the longitudinal direction along one longitudinal edge of the work table and the traverse is mounted at one end on a carriage that can slide along this rod. At its opposite end the traverse has a clamp that can solidly grip the corresponding table edge.
  • the table is provided adjacent the guide rod with a massive square-section bar formed with an upwardly open T-slot and a T-bolt or ratchet is fitted to the carriage so that the traverse can be latched along this edge of the table also.
  • a double angle iron is fixed to this slotted bar to secure it to the table and the guide rod is also secured to this angle bracket.
  • German patent 3,507,047 of P. Maier describes a stop arrangement for a table saw which has a complex metallic profile whose one end is secured to the table's miter slide and whose other end stands on a separate stand remote from the table to guide long workpieces.
  • the dangling free end of this system is not stable enough for use with a stamping machine or the like, and in general it is not usable as a holder for a workpiece in this type of equipment.
  • a workpiece-treating machine having a table with a pair of longitudinal edges and a working station between the edges has an apparatus for positioning a workpiece in the station which in turn has a generally square section metal tube extending along on edge of the table and formed with a longitudinally extending inner T-slot in which the one edge of the table is seated, a pair of transversely spaced but longitudinally extending and upwardly open outer T-slots, and a pair of outwardly open and longitudinally extending outer T-slots.
  • a longitudinally extending guide rod is supported at the one table edge and T-fasteners fix the guide rod on the table in the outwardly open T-slots at the one edge in a position extending parallel to the longitudinal edges.
  • a carriage longitudinally displaceable along the guide rod is fixed to one end of an elongated traverse extending transverse to the longitudinal edges.
  • a stepless-adjustment clamp on the carriage has a T-fastener engaged in one of the upwardly open T-slots for clamping the carriage on the tube at any position therealong and a toothed retaining element on the carriage engaged in the other upwardly open T-slot can arrest the carriage at any of a plurality of longitudinally offset positions therealong.
  • This slotted tube therefore fulfills several functions, namely carrying the guide rod, acting as a track for the two clamps, and rigidifying the table edge. It eliminates the need for separate brackets or flanges to support the guide rod, and ensures that the guide rod is perfectly parallel to the clamp tracks.
  • the tube is formed as a single unitary piece with the slots, produced by extrusion. This ensures that the slots are perfectly parallel to each other.
  • the T-fasteners each include a T-bolt having a head engaged in the respective slot, or a bolt and a nut threaded on the bolt and engaged in the respective slot.
  • a distance gauge is provided along at least one of outer slots.
  • FIG. 1 is an end view of the apparatus of this invention
  • FIG. 2 is a top view of the apparatus
  • FIG. 3 is a section taken along line III--III of FIG. 2.
  • the system of this invention is used on a flat and normally horizontally work table 1 having longitudinal edges extending perpendicular to the plane of the view in FIG. 1 and provided between these edges with a work station M, here provided with a only partially shown stamping device 16.
  • a traverse bar 2 extends crosswise across the table 2 and has an outer end that can be secured by a clamp 17 to the outer longitudinal table edge.
  • Workpiece holders 3 are provided along this traverse 2.
  • the tube 4 is also formed on its upper surface at a level somewhat above that of the slot 13 with two further T-slots 11 and 12 both extending longitudinally and opening at a surface of the tube 4 flush with the upper surface of the table 1.
  • the slot 11 is engaged by a T-bolt 20 of a stepless adjustment device 7 so that the traverse 2 can be arrested at any longitudinal position on the table 1.
  • This slot 11 is provided with a gauge strip 21 so that the exact position of the traverse 2 can be read or set by means of this strip 21.
  • the other slot 12 is provided with toothed inserts 15 engageable by a detent or catch 8 serving to arrest the traverse at any of a multiplicity of predefined longitudinally offset positions on the table 1.
  • single bar 4 serves several purposes:
